PEC12-2230F-S0024 Rotary Encoder Mechanical 24PPR Equivalent & Substitute Parts

Part Overview

The PEC12-2230F-S0024 is a mechanical rotary encoder manufactured by Bourns Inc., classified as a quadrature (incremental) output device with 24 pulses per revolution. This part is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives from active product lines. The encoder features a 6mm diameter flatted end actuator, integrated detent mechanism, built-in switch, and right-angle PCB through-hole mounting with PC pin termination. With a rotational life rating of 30,000 cycles minimum and ROHS3 compliance, substitute parts must maintain these core electrical and mechanical specifications to ensure direct compatibility in existing designs.

Substitute Part Grouping Explanation

Substitute parts for the PEC12-2230F-S0024 are grouped based on strict equivalence of the following critical parameters: encoder type (mechanical), output type (quadrature incremental), pulses per revolution (24), actuator type (6mm diameter flatted end), detent presence, built-in switch, mounting configuration (PCB through-hole right angle), termination style (PC pin), and rotational life rating (30K cycles minimum).

Direct substitutes maintain all parameters identically and differ only in product status (active versus obsolete) and packaging format. These parts are sourced from the active PEC12R series by Bourns Inc., which represents the current production equivalent to the obsolete PEC12 series.

Similar substitutes share the same mechanical and electrical architecture but differ in pulses per revolution (12 PPR instead of 24 PPR) or manufacturer (TT Electronics/BI EN12 series). These parts are functionally compatible only in applications where the lower resolution or alternative manufacturer specification is acceptable.

Engineering Selection Recommendations

For direct replacement of the obsolete PEC12-2230F-S0024, select from the active PEC12R series 24 PPR variants: PEC12R-2230F-S0024, PEC12R-2225F-S0024, PEC12R-2220F-S0024, PEC12R-2217F-S0024, or PEC12R-2125F-S0024. All maintain identical electrical and mechanical specifications, ROHS3 compliance, and 30,000-cycle rotational life rating. These parts differ only in internal mechanical configuration (indicated by the middle digit sequence), which does not affect functional compatibility for standard quadrature encoder applications.

The PEC12R-2230F-S0024 represents the closest direct equivalent, maintaining the identical part number structure within the active product line. All Bourns PEC12R variants listed are suitable for applications requiring 24 PPR resolution.

For applications where 12 PPR resolution is acceptable, the PEC12R 12 PPR variants (PEC12R-2117F-S0012, PEC12R-2120F-S0012, PEC12R-2125F-S0012, PEC12R-2130F-S0012) and the TT Electronics EN12-VS11AF18 are functionally compatible alternatives. The EN12-VS11AF18 maintains equivalent mechanical and electrical performance with RoHS compliance, though it represents a different manufacturer source.

Frequently Asked Questions (FAQ)

Q: Can PEC12R series parts directly replace the obsolete PEC12-2230F-S0024?

A: Yes. The PEC12R series represents the active production line equivalent to the obsolete PEC12 series. All PEC12R 24 PPR variants maintain identical encoder type, output type, resolution, actuator geometry, detent mechanism, built-in switch, mounting configuration, termination style, and rotational life specifications. Substitution is direct for all applications originally designed for PEC12-2230F-S0024.

Q: What is the difference between the various PEC12R-22xxF-S0024 part numbers?

A: The middle digit sequence (22xx) indicates internal mechanical configuration differences that do not affect electrical output or functional compatibility. All variants produce identical quadrature output at 24 PPR with the same mechanical interface. Selection among these variants depends on mechanical design requirements not specified in the electrical parameters.

Q: Can 12 PPR encoders replace the 24 PPR PEC12-2230F-S0024?

A: Only if the application design accommodates half the resolution. The 12 PPR variants (PEC12R-2117F-S0012, PEC12R-2120F-S0012, PEC12R-2125F-S0012, PEC12R-2130F-S0012, EN12-VS11AF18) maintain all other mechanical and electrical specifications but output 12 pulses per revolution instead of 24. This substitution requires confirmation that the lower resolution meets application requirements.

Q: Is the TT Electronics EN12-VS11AF18 compatible with the original PEC12-2230F-S0024?

A: The EN12-VS11AF18 is a 12 PPR alternative from a different manufacturer. It maintains identical mechanical mounting, actuator type, detent, built-in switch, right-angle orientation, PC pin termination, and 30,000-cycle rotational life. Compatibility depends on whether 12 PPR resolution is acceptable for the application. RoHS compliance is confirmed for this part.

Q: What packaging format should be specified for production orders?

A: All active substitute parts are supplied in Tray packaging. The original PEC12-2230F-S0024 packaging format is not specified in available data. Confirm packaging requirements with procurement specifications before finalizing orders.

Q: Are all listed substitutes in current stock?

A: Yes. All PEC12R variants and the EN12-VS11AF18 are listed as active products with confirmed inventory. The PEC12-2230F-S0024 (1133 pcs) and PEC12R-2230F-S0024 (2029 pcs) have the highest availability for immediate procurement.
